Researchers hope that by searching the tomb of British poet Fulke Greville (1554-1628), they will find definitive evidence that Greville penned some or all of Shakespeare’s works, reports the Telegraph. Radar evidence has supported suspicions that Greville is housing manuscripts in his lavish tomb. Researchers expect to find a copy of Shakespeare’s Antony and Cleopatra. Greville is one of many suspected in the timeworn debate over who penned Shakespeare’s works; other hopefuls include Christopher Marlowe, Edward de Vere and Francis Bacon.

Church officials oppose raiding the grave on “ethical grounds,” and even if researchers find a way in, it is unlikely they will find anything definitive. It doesn’t exactly stand to reason that Greville would masquerade his best work as someone else’s, and this could be a lot of wishful thinking (Edward de Vere, for example, had sensitive political ties, and so would have had a reason for generating a pseudonym). Yet there is evidence suggesting Greville was something of a prankster who left hidden messages in his writings, and who spent the equivalent of a half-million dollars on his tomb; historian AWL Saunders is quoted as stating, “Nobody would build something like that and leave it empty. There is definitely something down there and we want to find out what it is.”

Other evidence includes Greville’s knowledge of Rosicrucian philosophy, which many scholars agree would have been prerequisite in composing The Tempest.
